What do boric acid suppositories do are a treatment for yeast infections and bacterial vaginosis. They are safe for most people when used properly, but misuse could be dangerous.
How They Work
Boric acid is a weak acid that helps to maintain a healthy vaginal pH (a measure of how acidic the body’s natural environment is). It kills or prevents the growth of certain bacteria and fungi, so it can help treat recurring yeast and bacterial vaginal infections, says Dr. Rachel Dweck, MD, director of women’s health services at The Ohio State University Wexner Medical Center.
When They’re Used Correctly
The best way to use a boric acid suppository is to insert one in your vagina each day as directed on the product packaging and/or by your healthcare provider. Keep in mind that these suppositories may leak, so it’s important to keep the vagina clean and dry.
The Benefits and Risks of Using Boric Acid Suppositories for Vaginal Health
If you’re using a boric acid suppository for a BV infection, do not have sex during the treatment period because it can make your symptoms worse. This is especially true if you’re taking blood thinners, such as warfarin, which can put you at higher risk of bleeding.
When They’re Not Used Right
If a boric acid suppository does not cure your yeast or BV infection after a few days, talk to your doctor about whether it’s a good treatment for you. It’s not the first line of treatment, and it should only be used when standard treatments haven’t worked or you are at high risk for complications with antibiotics.
